SIPI-ION FOR ELEVATING WATER, 85o; i

Specification of Letters Patent No.. 5,105', dated May 8, 1847.

To all whom t may concern Be it known that I, AsAHEL ALDRICH, of Douglass, in the county of Worcesterv and State kof Massachusetts, have made a new and useful Improvement in Hydraulic Machinery, by which improvement what I denominate a yself-acting intermitting siphon is made to raise and deliver a portion of water atl the height of twenty or thirtyfeet above its source, so as to supply a quantity sufficient for ordinary domestic purposes; and I do hereby declare that the followingA is a full rand exact description 1J J thereof.

The conditio-ns necessary to the rendering of my apparatus effective 'are that the longer leg of the siphon shouldv considerably exceed that of t-he shorter leg, the quantity of water f v ceiver-C, to be filled with water, the operathat may be supplied by the machine being dependent on this eXtra length, and upon the diameter of the tube of the siphon. Iny

the situation in which this apparatus is applied, the reservoir, or source from which the supply of water is obtained must therefore be sufficiently elevated above the opening ofthe longer leg to admit of its neces` sary extension; the end ofthis should be kept immersed in water.

In the accompanying drawingFigure 1,` is a vertical section through the middle of. the apparatus when ready for operation..v

i Fig. 2, is a top view of it with the siphon,

and a top plate through which said. siphon is to pass, removed. These two figures may be considered as representing a 'machine of ordinary size, drawn on a scale of one eighth .of lan inch to the foot. Fig. 3, is a perspective view of the parts shown in F ig.2, but

drawn on. a larger scale; Figs. 4 and 5 show certain parts in detail.

In each of these figures where ythe same parts are represented they are designated by the same letters of reference. Y

A Fig. 1, is the longer, and B the shorter, leg of the siphon. C, C, is what I will denominate the closed receiver. The legs A, and B, are attached at their'upper ends to t-he top or cover D, of this receiver, which must be perfectly air tight.

E, and F, are valves lthat serveI to close the upper ends of the siphon legs. These are borne up by springs a, a, and remain closed during the intermitt-ing of the siphon; they are opened at the proper time in a manner to be presently described.

G is what I denominate the open receiver;

by va spring c; through this air is to be admitted when water is discharged 'from the receiver. The closed receiver rests: upon,

cover D, of theclosed and is made fast to, a stout rim, or supports It willl be manifest imder the arrangement shown in-the section Fig. 1, thatl were the-respective valves H and I, tobe closed, and'thetwo Siphon valves E, and F, opened, jp-

and ythetwo legs of the Siphon, and they retion would be the same with that ofjthe lcommon siphon, the receiver c, being a mere enlargement of the siphontube vin that part. f

of the legs A, and B to be allowed to dip` into water, as no air could then enter them,

the vwater which they contained would regij; main there, provided their length was .no 4

greater than/is 'admitted by the pressure Vof the atmosphere; and ifwhile so situated the .Valves H and I, were' opened, air would enter at t-he former, and water wouldbe./%fl discharged through theflatter int'ofthe open`r reservoir. If the' quantity of water so discharged be somewhat lessl than thatwhich d would be conta-ined in that part of the longer i' f leg of thefsiphon that extends ybelow the a` shorter leg, the two valvesH and I maybe closed, and the two valves E and F maybe opened, thek siphon will again operatepin this case theair which yhas been admitted into theV 'closed receiver will, of course, be f f,

equal to the volume 'of water. thatI hasbeen dischargedfrom it, and this air will,`owing to the direction of this current, first enter the discharging branch, having thelonger leg A; this columnof air having entered," it .1k

willrbe followed by one of water. Let the column of air in 'the leg A, be equal in length to u, the line u, being level with the termination of theshorter leg, and supposing the length of the longer legto eXceedthat of thevshorter bythe distance u, w, the column of water in the longer leg will exceed that or u, y, and aft-er this column of air has been '."4 in the shorter by the distance between @,w, i'

discharged, this discharge being due to the greater length of the column of water in the longer leg, the siphon will continue to operate, the closed receiver C, C, being again filled with water; and when this has taken place a portion of water may again be discharged into the open. receiver, and so on continuously. It is this portion thus discharged, during the intermission of the siphon thatis to give the supply required. for family use, and that is, also to furnish the necessary power for openingv and clos-` ing the respective valves. The arrangementof the apparatus for producing this latter ei'ect I will now proceed to describe.

K, andL, (Figs. 2 and 3) are two spouts, or tubes through 'which water is to be discharged, alternately, from the open receiver Gr. This water is to run into two tilting dishes M, and N, that are sustained on the opposite ends of a vibrating lever of equal arms, O, O, having its fulcrum at'd. The dishes M, and N, work on joint pins at 66,

so as to be capable oit tilting, and are` so balanced that when in their most elevated posi# tion they will remain on alevel, but when the end of the lever to which they are aty tached is depressed they willtilt and pour out the water which they have received, and

this running into a trough, or other recep-v tacle, xed forv `the purpose may be taken A for use; n, a, are screw rods thatmay be raised or lowered to regulate the tilting ot the dishes. The spoutsK, and L, are, as has been stated, to discharge-water alternately, and to cause them to do this, their inner openings, within the receiver Gr, Gr, must be alternately opened and closed by valves, and this may be effected in the folf lowingmanner:V P, and Q, (Fig. 2) are two valves that open and close the spouts. rlfhese are also shown injFig. 4, which is a view of the inner side of a sectional part of the frim of the receiver G, G, say betweenthe points f, f, of Fig. 3. K', and L', in. Fig-4, are the inner terminations of the spouts. The

" valves P, and Q, are held down by springs g, and L. The valve Q, is atythe end of a lever i, z', and the valve'P, at the end of the lever y', each of which levers has its ulcrum at K. How these valves are` alternately opened will presently appear. j

Y R, R, is a lever that is bentV twice at right angles and that serves to regulate the opening and closing of the respective valves. The outer end of this lever is connected to avertical rod S, that serves to vibrate it, as the lever O, O, vibrates; the rod S being j oi'nted to said lever.- Fig.` 5-shows the lever R, R, with no more of its connections than are necessary to exemplify its action; Z, is

" its fulcrum within the receiver Gr, Gr, and Vat m, it is jointed .to a sliding rod T, that passes through a stuffing box; the operation. and use of this sliding rod will be seen by referring to the section Fig.` 1, where it is shown as carrying the cross-head 0, o, that serves, when depressed, to open the siphon valves P F, which opening takes place when the siphon is to come into action after a period of intermission. The valves H, and I, areV made to operate by means of a lever VU, .U, situated within the closed receiver C, C. Thisr lever is seen in Figs. 1, 2 and?) it works on a joint pin p (Fig. 3) -at its middle, and its two ends bear upon the stems ofthe'valves and overcomel the force of the` springs by which they are otherwise kept closed. `The valves H and I, are to be opened at thesame time that the valves of the siphon are closed, and the same cross head o, 0, operates the four valves. A linger g, proceeds from the cross-head, and passes under that end of the lever U, that is toopen the valve I, and as this end -is raised ,the

.other vend will be depressed, andthe two valves will be opened, simultaneously with.

the closing of the siphon valves. p

The valvesP', and Q, appertaining` to the spouts K and L, are alsoopened by the leven R; this is effected by. means of a lpin r, (Figs. 4 and 5) that projects from said lever vbetween the two levers i and y', Fig. 4; when theleverV R, is raised the pin 7, will `he brought into contactwith the `lever j, having the valve P,.at itsend, which willbe raised; and when the leverv R, is depressed it will bebroughtinto contact with the end z", of the lever i, and the valve Q will. be raised. These two valves it will-he observed act independently, as one of rthemis tobe -closed during the whole of the time that the Y. Having thus fully described the manner in which Il construct my apparatusfor raising` and' supplying 'a portion of water by Vmeans of an intermitting siphon, 4.at 1the height -of a number of. feet above its source,- and having explained the operationotthe respective parts thereof, what I claim therein as new and desire tosecure by Let` ters Patent is The combining of the` siphon with a closed receiver in such `manner as that said receiver shall constitute an enlargement of the siphon at `the height to which the` water is to be raised; the longer and shorter legs of the siphon beingpso proportioned to each other as that the latter'shall be capable of receiving within it a column of air from the closed receiver equal in volume to that which has been drawn therefrom, for the purpose and in the manner described, while said longer leg shall still contain a column of water more than sufficient to counterbalance the length of the column in the shorter leg; under which 'arrangement said column of air is discharged, and the, closed receivers refilled preparatory to another intermission of the siphon for the discharge of water struction of this apparatus to the precise f form of the respective parts as herein' described and represented, but toV vary these as i.

I may think proper, While the principle ofaction and the useful result thereby attained remain, in substance, unchanged.
